I don't know how many of these meetings or conversations other people have. I have several a week. I've described them elsewhere. I some meetings I can have speakers who say the following when you're doing the round of introductions.
"I'm [X], my pronouns are [several]. I live with ADHD, this may manifest as taking thought breaks. If I delay before responding, please don't speak as it interrupts my thought and may trigger mutism. I have rejection sensitivity dysphoria so consider how you frame responses to me." and it goes on. Usually, a couple of (mental) health conditions and maybe even a physical description: "I have [Y]-length, [colour] hair, with [X]-coloured eyes".
Add in the number of people who tell you about the land on which their institution stands, the displaced people, various historical treaties…it genuinely cuts down on any meeting time if there are several speakers. (I do mean virtual as well as in-person.)
There are people who watch you, particularly when specific members speak in order to "call you out" for signs of not appearing to be adequately engaged and therefore displaying unconscious bias or something worse.
There are people who interrupt every time someone uses a pronoun incorrectly or challenges people who opt for 'they' all the time rather than switch between 'they' and 'she' as given in the tiny name and pronoun chyrons.
But those meetings are so interrupted I can scarcely keep a coherent chain of thought. The productivity is nowhere at times.
Helen Joyce may well have even more of those meetings or conversations that I do. I can understand her position and personal decision.
And I still recognise that selective use of indulgences like friend-based pronouns rather than sex-based has contributed to the mess that we're in with the law and even having discussions.
